The newer of KSC's two IMAX 3-D films tells the inspiring story of the Hubble Space Telescope, as narrated by Leonardo DeCaprio. The crews of Shuttle Atlantis's mission STS-125 brought an IMAX 3-D camera on board to document their painstaking spacewalk repairs of the most complex optical device ever built.

Due to the weight of the film, only 8½ minutes of footage could be shot in space; it is fleshed out with earthbound footage, and stunning computer-generated flythroughs of helix and butterfly nebulas as detected by Hubble's historic lens. Both films are first rate, so select the smarmy celebrity narrator you prefer.
